Abstract
The utility model discloses a kind of rotator mixer gear reduction unit used, under being arranged on the chassis of sand muller, comprise the casing with the chassis integrally casting of sand muller, the scraper shaft of sand muller vertically puts in casing the output shaft doubling as speed reducer, the end winding support that described scraper shaft puts in casing has large helical gear, the input shaft of input power puts in casing from casing side level, supporting axle is provided with in casing, the input shaft end being positioned at casing is fixed with bevel pinion, back shaft is coaxially provided with: with the bevel gear wheel of bevel pinion engagement driving, with the bevel pinion of large helical gear engagement driving.Box body of speed reducer and sand muller chassis whole are cast by the utility model, simplify manufacturing process, and speed reducer overall structure becomes compacter.Utilize the large helical gear in the scraper shaft installation speed reducer of sand muller, decrease intermediate transfer link, improve transmission efficiency, decrease assembling work amount simultaneously, make the transmission process of speed reducer become succinct efficient.
Description
Technical field
The utility model relates to speed reducer technical field, the gear reduction unit that especially a kind of rotator mixer is used.
Background technique
Rotator mixer is as the nucleus equipment of foundry sand process, and the mulling efficiency higher because of it and Quality of Mixing Sand, be used widely at present on foundry sand process for producing line.Gear-box is the important mechanical part of sand muller transmission device one, and the Choice and design of its structure and component just seems and is even more important.Current sand muller generally adopts full-height tooth roller box as its transmission hinge, needs to make the base matched during installation.This structure causes the service clearance of speed reducer comparatively limited.Reduction gearbox output shaft end need adopt coupling to be connected with the input shaft on sand muller chassis, and cause this joint accuracy of manufacturing to strengthen, assembling difficulty, occupies larger space, and transmission efficiency is also lower simultaneously.
Model utility content
The problem that the utility model technology will solve is: overcome the deficiency in prior art, provides a kind of rotator mixer gear reduction unit used.
The utility model solves the technological scheme that its technical problem adopts: a kind of rotator mixer gear reduction unit used, under being arranged on the chassis of sand muller, comprise the casing with the chassis integrally casting of sand muller, the scraper shaft of sand muller vertically puts in casing the output shaft doubling as speed reducer, the end winding support that described scraper shaft puts in casing has large helical gear, the input shaft of input power puts in casing from casing side level, supporting axle is provided with in casing, the input shaft end being positioned at casing is fixed with bevel pinion, back shaft is coaxially provided with: with the bevel gear wheel of bevel pinion engagement driving, with the bevel pinion of large helical gear engagement driving.
For improving the wear resistance bottom sand muller chassis and box body of speed reducer, described chassis is coated with Wear-resisting bottom plate.
The beneficial effects of the utility model are: box body of speed reducer and sand muller chassis whole are cast by the utility model, and simplify manufacturing process, material capability easily controls, and speed reducer overall structure becomes compacter.Directly utilize the large helical gear in the scraper shaft installation speed reducer of sand muller, thus decrease intermediate transfer link, improve transmission efficiency, decrease assembling work amount simultaneously, make the transmission process of speed reducer become succinct efficient.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of rotator mixer gear reduction unit used as shown in Figure 1, be arranged on the chassis 1 time of sand muller, comprise the casing 2 with chassis 1 integrally casting of sand muller, the scraper shaft 3 of sand muller vertically puts in the output shaft doubling as speed reducer in casing 2, described chassis 1 is coated with Wear-resisting bottom plate 10, with the wear resistance bottom the casing 2 on the chassis 1 of improving sand muller also i.e. speed reducer.
The end winding support that described scraper shaft 3 puts in casing 2 has large helical gear 4, the input shaft 5 of input power puts in casing 2 from casing 2 side level, supporting axle 6 is provided with in casing 2, input shaft 5 end winding support being positioned at casing 2 has bevel pinion 7, and back shaft 6 is coaxially provided with: with the bevel gear wheel 8 of bevel pinion 7 engagement driving, the bevel pinion 9 with large helical gear 4 engagement driving.
Described input shaft 5, supporting axle 6 and scraper shaft 3 all by corresponding bearings on casing 2.
The input shaft 5 of speed reducer is connected to transmission pulley and input power, changes transmission direction and rotating speed, complete the stirring operation to casting sand in sand muller by speed reducer transmission.Because casing 2 and the chassis 1 of sand muller are one piece castings, make manufacturing process become simple, and material capability easily controls, speed reducer overall structure becomes compacter.Large helical gear 4 is arranged on the scraper shaft 3 of sand muller, decreases intermediate transfer link, improves transmission efficiency, decreases assembling work amount, makes the transmission process of speed reducer become succinct efficient.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
